More things have broken with it! I guess 20+ years is a good run.
The whole shebang will cost more than my dental work, which leaves me with mixed feelings on multiple topics.
Swapping the units out does present some issues. I have the knowledge & skills (I've helped replace those more than once), but I do not have the ability (they are physically too much for me). Husband is willing to pay for install & haul away, though this does not solve my anxiety about strangers inside the house. Fingers crossed it goes well!
